Abstract

Ein Haltemagnetauslöser für Fehlerstromschutzschalter besitzt einen aus zwei L-förmigen Polblechen (2 und 3) bestehenden Jochkörper (1), in dem ein Fenster (8) zur Aufnahme einer Spulenwicklung vorgesehen ist. Im Bereich des Fensters (8) ist eine die Ankerauflage (10) bildende Erhebung (11) vorgesehen. Die Erhebung (11) ist kürzer als die Breite (B) des Fensters (8), so daß der für das Erreichen der Sättigung maßgebende Querschnitt des das Fenster (8) auf der Seite des Ankers (14) begrenzenden Steges (22) von der Höhe der die Ankerauflage (10) bildenden Erhebung (11) unab­ hängig ist. A holding magnet release for residual current circuit breakers has one of two L-shaped pole plates (2 and 3) existing yoke body (1), in which a window (8) is provided for receiving a coil winding. in the The area of the window (8) is the anchor support (10) educational survey (11) provided. The assessment (11) is shorter than the width (B) of the window (8), so that the one decisive for reaching saturation Cross section of the window (8) on the side of the Anchor (14) delimiting web (22) from the height of the the anchor support (10) forming elevation (11) pending.
